A glass melting installation and a method of operation of this with a melting tank, with burners for fossil fuels and with at least one regenerator for preheating oxidation gases, whereby between the at least one regenerator and the melting tank at least two step-free port necks are provided for the alternating supply of oxidation gases and the removal of combustion gases, and whereby the port necks are provided with lateral supply openings for the supply of secondary oxidation gases. In order to achieve injection into the waste gas flow without directional influence, with a simple construction and good energy usage, the supply openings for the supply of secondary oxidation gases are perpendicular to the free cross-section of the port necks above the step-free bottom surfaces.
